Hi,
I was wanting to include a listw list of neighbours for USA states which include Alaska and Hawaii with Alaska a neighbour for Washington and Oregon states and Hawaii a neighbour for California and the Western continental US states. Naturally queen relationships fail. The Albers shapefiles at this URL are really useful for general mapping purposes but result in erroneous relationships with k-nearest neighbours when this is performed in GeoDa. These maps have Hawaii and Alaska elided to south of Texas. <https://github.com/hrbrmstr/albersusa> https://github.com/hrbrmstr/albersusa When one uses the native map - with unelided states - available from the URL below - then k-nearest neighbours also does not work properly in GeoDa. I also want to extend this to the SAMHSA substate shapefile found at this URL for the 395 substate areas used by the USA National Survey of Drug Use and Health within SAMHSA. <https://www.samhsa.gov/data/report/2014-2016-nsduh-substate-region-shapefil e> https://www.samhsa.gov/data/report/2014-2016-nsduh-substate-region-shapefile I did see that someone was able to create relationships across a straight for Italy although I am not quite sure how this was accomplished technically. I would be grateful for any help you could provide. Thankyou so much, Stuart Reece.
